"binary expressions" are documents
Authored by: Anonymous on Wednesday, April 25 2012 @ 12:42 PM EDT
OKay then they're documents.


TBF they do appear to 50 pages of hexadecimal dump for the purpose of
registration. (and more properly called object code rather than binary
expression)

http://www.copyright.gov/eco/help-deposit.html#object
though I would note this..

"which is generally the code translated from the original programming
language and compiled by a computer into a machine-readable hexadecimal (octal,
or binary) representation."

so my "binary expression" idiom is not wide of the mark and could be
seen as less narrow than "binary representation"

Re: Here's a seperate question...
Authored by: Gringo_ on Wednesday, April 25 2012 @ 03:45 PM EDT

Here's a separate question: Has anyone implemented a usable architecture switching de/re-compiler? (ie, you feed in x86 machine code on one end, and it outputs ARM machine code from the other) Theoretically possible, but I don't know the specifics well enough to know how practical.

Probably not that difficult to translate between instruction sets, but much more is needed. We might assume you would like to translate a program written for one platform to a form that can run on another. Suddenly we run into all kinds of problems above and beyond translating the instruction set. We need to "unlink" the code as well, and relink it in the format expected by the target platform. This is not a job done by a compiler, obviously, but rather, done by a linker if one existed that can translate link formats. Finally, supposing we did all that, system and OS API calls will be different on the two platforms, so the job is hopeless.

What might be translatable might be a block of pure code, with no system calls - in the form of an object file. Then, we still need to translate file formats, so that when we compile the translated object code on the new platform will understand it.
